Product details
Overview
AP7366EA-10SN-7 from Diodes Incorporated is a 600mA, fixed-output 1.0V low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at 600mA, and 75dB PSRR at 1kHz. It integrates enable control, thermal shutdown, and current limiting, and is optimized for battery-powered systems requiring stable low-voltage core supply.
For engineers reviewing the AP7366EA-10SN-7 datasheet, AP7366EA-10SN-7 pinout, AP7366EA-10SN-7 application, or AP7366EA-10SN-7 equivalent, this page delivers verified electrical parameters, validated package mapping, confirmed pin functions, and real-world use context for portable, FPGA, and low-power embedded designs.
Technical Context
The AP7366EA-10SN-7 uses a PMOS pass transistor architecture enabling ultra-low dropout (300mV @ 600mA) and high PSRR (75dB @ 1kHz), with internal 0.8V bandgap reference and error amplifier for precise output regulation. Its EN pin provides active-high logic control with 1.0V VIH threshold and 3MΩ internal pull-down resistor.
Thermal protection activates at +150°C junction temperature with +20°C hysteresis, and short-circuit current is clamped to ~250mA. The device remains stable with only 1μF ceramic output capacitance and operates across -40°C to +85°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±15mV accuracy at 10mA load ensures reliable core voltage for low-voltage logic and I/O domains. |
| Max Output Current | 600mA continuous delivery supports power rails for microcontrollers, sensors, and FPGA I/O banks without external boost stages. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on IoT nodes powered by coin cells or Li-SOCl₂ batteries. |
| Dropout Voltage | 300mV at 600mA allows operation from 1.3V input - critical for single-cell LiFePO₄ or dual-cell alkaline systems. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters, preserving signal integrity in mixed-signal SoCs. |
| Start-up Time | 150μs fast enable supports dynamic power sequencing in multi-rail systems and low-latency wake-from-sleep transitions. |
| Thermal Shutdown | +150°C trip point with +20°C hysteresis prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
AP7366EA-10SN-7 is housed in a 2.0mm × 2.0mm × 0.6mm U-DFN2020-6 package with wettable flank leads and exposed thermal pad (pin 2). The package supports high-density layout and efficient heat dissipation (θJA = 46.2°C/W on JEDEC-standard board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.2V–6V; requires ≥1μF MLCC bypass to GND within 2mm for EMI suppression and transient stability. |
| GND (Pin 2) | Power ground reference | Connects to PCB thermal pad and main ground plane; essential for thermal performance and noise rejection. |
| EN (Pin 1) | Enable control input | Active-high logic interface (VIH ≥1.0V); internal 3MΩ pull-down ensures default OFF state if left unconnected. |
| OUT (Pin 4) | Regulated output | Delivers 1.0V ±15mV; requires ≥1μF ceramic capacitor placed <1mm from OUT/GND pins for transient response and stability. |
| ADJ (Pin 6) | Feedback reference node | Internally tied to 0.8V reference; must be connected to GND for fixed-output variants like AP7366EA-10SN-7. |
| NC (Pin 5) | No internal connection | Floating or grounded - no electrical impact; recommended to tie to GND for mechanical robustness and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ with full functionality | 60μA quiescent current maintained across full 2.2V–6V input range and 0–600mA load, enabling true "zero-power" standby modes. |
| Ultra-stable with minimal capacitance | Guaranteed stability using only 1μF ceramic output capacitor - eliminates need for bulk electrolytics and saves board space. |
| Fast transient recovery | Load step response (100mA→500mA) shows <20mV undershoot/overshoot and <200μs settling time, protecting sensitive analog circuitry. |
| Integrated fault protection | Combines foldback current limit (~250mA short-circuit clamp), thermal shutdown (+150°C), and safe EN pin leakage (<0.1μA). |
| Automotive-ready construction | Totally lead-free, halogen-free, and RoHS 3 compliant; qualified per AEC-Q100 stress testing upon request for automotive-grade deployment. |
Applications
| Wearable Sensor Node | FPGA I/O Bank Supply |
|---|---|
|
Use Scenario: Compact wearable health monitor with BLE SoC, optical heart-rate sensor, and rechargeable Li-ion cell. IC Role / Device Role / Timing Role: Primary 1.0V LDO supplying digital core and sensor interface logic, enabled only during active measurement cycles. Use Value: 60μA IQ extends battery runtime beyond 14 days; 150μs start-up enables rapid sensor activation without system-level latency penalties. |
Use Scenario: Industrial FPGA-based motor controller requiring clean, sequenced I/O voltage for LVCMOS18 interfaces. IC Role / Device Role / Timing Role: Dedicated 1.0V rail generator for FPGA bank powering isolated communication peripherals (RS-485 transceivers, CAN PHYs). Use Value: 75dB PSRR rejects noise from nearby 48V-to-12V buck converter; 300mV dropout permits direct derivation from shared 1.3V intermediate rail. |
| USB-C Power Delivery Sink | Smart Home MCU Subsystem |
|
Use Scenario: USB-C powered smart display with PD negotiation, display driver, and touch controller. IC Role / Device Role / Timing Role: Secondary 1.0V regulator for display timing controller (TCON) logic, enabled after PD contract establishes VBUS voltage. Use Value: EN pin synchronization ensures TCON power-up aligns precisely with display initialization sequence; thermal shutdown prevents latch-up during hot-plug events. |
Use Scenario: Battery-backed Zigbee coordinator with ARM Cortex-M0+ MCU, flash memory, and RF front-end. IC Role / Device Role / Timing Role: Main 1.0V supply for MCU core and embedded flash, managed via firmware-controlled EN pin for deep-sleep entry/exit. Use Value: No-load stability eliminates need for dummy loads; 1μF output cap reduces BOM count and improves reliability over tantalum alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ, fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-1002E/MB | Same 1.0V fixed output, but 2.5μA IQ (lower), 250mA max current (lower), SOT-23-5 package (larger footprint, higher θJA). | Limited to sub-250mA loads; insufficient for FPGA I/O or multi-sensor nodes requiring >300mA peak current. | Select when ultra-low IQ dominates over current capability and board space is unconstrained. |
| Torex XC6210B102MR-G | 1.0V fixed output, 1.5μA IQ, 300mA rating, SOT-25 package; lacks EN pin and thermal shutdown. | No enable control or fault protection - requires external logic and thermal monitoring for safety-critical deployments. | Choose only for cost-sensitive, non-safety applications where external supervision is already implemented. |
Compared with MCP1703T-1002E/MB and XC6210B102MR-G, AP7366EA-10SN-7 uniquely balances 600mA drive, 60μA IQ, integrated EN, and full fault protection in a 2mm² DFN - making it optimal for space-constrained, battery-operated systems needing both performance and robustness.

FAQ
What is the minimum input voltage required for AP7366EA-10SN-7 to regulate 1.0V output at 600mA?
The minimum input voltage is 1.3V, derived from the 300mV dropout specification at 600mA load. At lower inputs (e.g., 1.25V), output voltage collapses below 1.0V due to insufficient headroom. Operation is guaranteed only above VIN ≥ VOUT + VDROPOUT across the full temperature range.
Can AP7366EA-10SN-7 operate without an output capacitor?
No - a minimum 1μF ceramic capacitor is mandatory between OUT and GND for stability, per datasheet Section 10. Omitting it causes oscillation and output voltage collapse. Larger values (e.g., 2.2μF) improve load transient response but are not required for basic regulation.
Is the ADJ pin functional in the AP7366EA-10SN-7 fixed-output variant?
No - in fixed-output versions like AP7366EA-10SN-7, the ADJ pin is internally connected to the 0.8V reference and must be externally tied to GND. Leaving it floating violates the absolute maximum rating and may cause regulation instability or increased IQ.
How does the EN pin behave during power-up when VIN ramps slowly?
The EN pin has a 1.0V VIH threshold and 3MΩ internal pull-down. If VIN rises slower than the EN signal (e.g., from a weak GPIO), the regulator may enter an undefined state until EN exceeds 1.0V. Best practice is to drive EN from a rail that reaches 1.0V before VIN stabilizes, or use a dedicated supervisor IC.
